15
16Eric Norum (eric@@skatter.usask.ca) has a driver for a parallel
17port interface to a BDM module.  This driver has a long history
18and is based on a driver by Gunter Magin (magin@@skil.camelot.de)
19which in turn was based on BD32 for DOS by Scott Howard.  Eric Norum
20and Chris Johns (ccj@@acm.org) have put together a package containing
21everything you need to use this BDM driver including software, PCB layouts,
22and machining drawings.  From the README:
23
24"This package contains everything you need to be able to run GDB on
25Linux and control a Motorola CPU32+ (68360) or Coldfire (5206, 5206e, or
265207) target through a standard PC parallel port."

28Information on this BDM driver is available at the following URL:

30@example

32@end example

34The package is officially hosted at Eric Norum's ftp site:

38@end example
39
40Peter Shoebridge (peter@@zeecube.com) has ported the Linux
41parallel port BDM driver from Eric Norum to Windows NT.  It is
42available at http://www.zeecube.com/bdm.
43
44The efi332 project has a home-built BDM module and gdb backend for
45Linux.  See http://efi332.eng.ohio-state.edu/efi332/hardware.html)
46for details.  The device driver and gdb backend are based on those
47by Gunter Magin (magin@@skil.camelot.de) available from
48ftp.lpr.e-technik.tu-muenchen.de.

50Pavel Pisa (pisa@@cmp.felk.cvut.cz) has one available at

53Huntsville Microsystems (HMI) has GDB support for their BDM module
54available upon request.  It is also available from their ftp site:

57The Macraigor OCD BDM module has a driver for Linux
58written by Gunter Magin (magin@@skil.camelot.de).

78@c "Adrian Bocaniciu" <a.bocaniciu@computer.org> has a driver
79@c for NT and is willing to share it but he needs to be emailed
80@c privately since he needs to explain somethings about it.
81@c It has been used for over a year as of 08/18/99.

83Christian Haan <chn@@intego.de> has written a driver for FreeBSD
84based for"a slightly changed ICD BDM module (because of changes
85in the BDM interface on the PowerPC)" that "probably will work with
86the PD module too."  His work is based on the M68K BDM work by
87Gunter Magin (Gunter.Magin@@skil.camelot.de) and
88the PPC BDM for Linux work by Sergey Drazhnikov (swd@@agua.comptek.ru).
89This is not yet publicly available.

91Sergey Drazhnikov (swd@@agua.comptek.ru) has written a PPC BDM driver for
92Linux.  Information is available at http://cyclone.parad.ru/ppcbdm.

94Huntsville Microsystems (HMI) has GDB support for their BDM module
95available upon request.  It is also available from their ftp site:
96ftp://ftp.hmi.com/pub/gdb
97
98GDB includes support for a set of primitives to support the Macraigor
99Wiggler (OCD BDM).  Unfortunately, this requires the use of a
100proprietary interface and is supported only on Windows.  This forces
101one to use CYGWIN.  Reports are that this results in a slow
102interface.  Scott Howard (http://www.objsw.com) has announced
103that support for the gdb+wiggler combination under DJGPP which should
104run significantly faster.
